Removing a button does not remove assigned OnClick Method

[AnNormalie]

When removing a button in the designer with an assigned on Click event the code gets not removed.

eg this gets not removed when removing the button.

protected async System.Threading.Tasks.Task Button0Click(MouseEventArgs args)
{
    UriHelper.NavigateTo("article");
}

The project and the button got generated by Radzen (not RBS)

We will probably have to ask the user if they want to delete any event handlers as this may not always be the case.

Radzen does that by default as the code of the event handler is generated from the component itself when the user clicks run.

I see.
Sounds good to me to ask the user if the related code should be deleted.
Would love to see this feature.
